Description

Technical Field

[0001] This utility model belongs to the field of power tool technology, and specifically relates to a rechargeable electric drill with a ring-shaped LED light strip structure. Background Technology

[0002] A cordless electric drill is a handheld power tool that uses lithium or nickel-cadmium batteries as its power source, and the batteries can be recharged repeatedly. It mainly uses a motor to drive the drill bit to perform drilling or screw fixing operations, and can complete the work without an external power source.

[0003] Currently, when using cordless electric drills in dark or poorly lit environments (such as inside cabinets, behind ceilings, or in confined spaces), operators often find it difficult to clearly observe the drilling position and progress, which can easily lead to inaccurate drilling positioning, drilling deviations, or even safety accidents. Furthermore, existing cordless electric drills only have a single LED light at the lower or upper front of the drill, resulting in limited illumination, severe shadows, and glare interference, making it still difficult for operators to clearly see the drilling point. Utility Model Content

[0004] The purpose of this utility model is to provide a rechargeable electric drill with a ring-shaped LED light strip structure. Its advantage is that it can provide uniform and shadowless lighting in low-light working environments, avoid operational errors and safety hazards caused by insufficient light, and improve work accuracy and safety.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rechargeable electric drill with a ring-shaped LED light strip structure, comprising a rechargeable electric drill body, a chuck threadedly connected to the front end of the rechargeable electric drill body, a decorative cover, a lamp cover, and a ring-shaped LED light strip respectively disposed between the rechargeable electric drill body and the chuck, the ring-shaped LED light strip being arranged at the front end of the rechargeable electric drill body, and the ring-shaped LED light strip being connected to a control switch inside the rechargeable electric drill body via a wire.

[0006] The above technical solution involves arranging multiple LED beads around the front end of the cordless electric drill body, which are connected to a control switch on the drill body. When the control switch is activated and the drill is turned on, the ring-shaped LED strip illuminates simultaneously. This provides uniform, shadowless lighting, allowing operators to clearly observe the drilling position, significantly improving drilling accuracy, reducing operational errors caused by insufficient light, ensuring adequate illumination while avoiding glare interference, and enhancing safety at the work site.

[0007] The present invention is further configured such that the annular LED light strip is composed of a flexible circuit board and multiple LED beads, wherein the LED beads are high-brightness surface-mount LED beads with a color temperature of 6000K and a brightness of 10-15 lumens.

[0008] Using the above technical solution: multiple LED beads arranged around the front end of the flexible circuit board can provide uniform shadowless illumination, making it easy for operators to clearly observe the drilling position.

[0009] The present invention is further configured such that a microcontroller is mounted on the flexible circuit board and is electrically connected to the rechargeable lithium battery of the rechargeable electric drill body through a control switch on the rechargeable electric drill body itself, and the control switch is a touch-sensitive electronic switch.

[0010] The above technical solution is adopted: the microcontroller is used to process the signal of the control switch and control the on and off of the ring LED light strip. When the control switch on the rechargeable electric drill body is turned on to start the electric drill, the microcontroller can synchronously control the ring LED light strip to light up for illumination.

[0011] The present invention is further configured such that the control switch controls the LED light bead switch through a microcontroller, the working voltage is 3.7V, and the rechargeable lithium battery provides a stable voltage to the LED light bead through a DC-DC converter with voltage regulation and anti-interference functions. The control switch has two modes: when the switch is lightly touched, the timing circuit is triggered, and the LED light strip keeps illuminating for 5 to 10 seconds and then automatically turns off; when the switch is pressed continuously, the LED light strip remains on until the switch is released.

[0012] By adopting the above technical solution, two on-state modes of the control switch can be activated as needed, and a stable voltage can be provided through a DC-DC converter to avoid voltage fluctuations affecting the lifespan of the LED beads.

[0013] The present invention is further configured such that the annular LED light strip is embedded in the groove of the lampshade and is snapped onto the front end of the rechargeable electric drill body using a snap-on installation structure. The lampshade is made of a transparent polycarbonate cover with a thickness of 1.5mm and a light transmittance of ≥90%.

[0014] The above technical solution ensures high light transparency while also providing wear and impact resistance, thus protecting the ring-shaped LED light strip.

[0015] The present invention is further configured such that a silicone sealing ring is snapped into the joint between the interior of the decorative cover and the lampshade, and the decorative cover and the lampshade are installed together on the side away from the annular LED light strip to form a sealed structure.

[0016] The above technical solution forms a sealed structure to prevent dust and liquid from entering, thus protecting the ring-shaped LED light strip.

[0017] The present invention is further configured such that screws are threadedly connected to the bottom of the decorative cover, lampshade, and annular LED light strip, and the decorative cover, lampshade, and annular LED light strip are connected to the front end of the rechargeable electric drill body by screws and bolts.

[0018] The above technical solution involves installing and fixing the decorative cover, lampshade, and ring-shaped LED light strip to the front end of the cordless electric drill body, which improves installation stability and allows for disassembly and replacement.

[0019] The present invention is further configured such that a copper layer in contact with the metal shell of the rechargeable electric drill body is fixedly connected to the side of the flexible circuit board near the body of the rechargeable electric drill body.

[0020] The above technical solution involves using LED light strips to conduct heat generated through a copper layer to the metal casing of the rechargeable electric drill body for heat dissipation.

[0021] In summary, this utility model has the following beneficial effects: By arranging multiple LED beads around the front of the cordless electric drill body and connecting them to the control switch on the drill body, the ring-shaped LED light strip illuminates simultaneously when the drill is turned on. This provides uniform, shadowless lighting, allowing the operator to clearly observe the drilling position, significantly improving drilling accuracy, reducing operational errors caused by insufficient light, ensuring adequate illumination while avoiding glare interference, and enhancing safety at the work site.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1: refer to Figure 1 , Figure 2 , Figure 3A rechargeable electric drill with a ring-shaped LED light strip structure includes a drill body 5, a chuck 1 threadedly connected to the front end of the drill body 5, a decorative cover 2, a lampshade 3, and a ring-shaped LED light strip 4 respectively disposed between the drill body 5 and the chuck 1. The ring-shaped LED light strip 4 is positioned at the front end of the drill body 5 and is connected to a control switch inside the drill body 5 via wires. By arranging multiple LED beads around the front end of the drill body 5 and connecting them to the control switch, the ring-shaped LED light strip 4 illuminates simultaneously when the drill is turned on. This provides uniform, shadowless illumination, allowing operators to clearly observe the drilling position, significantly improving drilling accuracy, reducing operational errors caused by insufficient light, ensuring sufficient illumination while avoiding glare interference, and enhancing safety at the work site.

[0026] refer to Figure 1 The ring-shaped LED light strip 4 consists of a flexible circuit board and multiple LED beads. The LED beads are high-brightness surface-mount LED beads with a color temperature of 6000K and a brightness of 10-15 lumens. The multiple LED beads arranged around the front end of the flexible circuit board can provide uniform shadowless illumination, making it easy for operators to clearly observe the drilling position.

[0027] refer to Figure 1 A microcontroller is mounted on the flexible circuit board and is electrically connected to the rechargeable lithium battery of the rechargeable drill body 5 via a control switch on the drill body 5. The control switch is a touch-sensitive electronic switch. The microcontroller processes the signal from the control switch and controls the on / off state of the ring LED light strip 4. When the control switch on the rechargeable drill body 5 is activated to start the drill, the microcontroller can simultaneously control the ring LED light strip 4 to light up for illumination.

[0028] refer to Figure 1 The control switch controls the LED beads via a microcontroller, operating at 3.7V. A DC-DC converter with voltage regulation and anti-interference functions ensures a stable voltage from the rechargeable lithium battery to the LED beads. The control switch has two modes: a light touch triggers a timer circuit, keeping the LED strip illuminated for 5-10 seconds before automatically turning off; a continuous press keeps the LED strip constantly lit until the switch is released. Both on / off modes can be activated as needed, and the stable voltage provided by the DC-DC converter prevents voltage fluctuations from affecting the LED bead lifespan.

[0029] refer to Figure 2 , Figure 3The ring-shaped LED light strip 4 is embedded in the groove of the lampshade 3 and is snapped onto the front end of the cordless electric drill body 5 using a snap-on installation structure. The lampshade 3 is made of polycarbonate transparent cover with a thickness of 1.5mm and a light transmittance of ≥90%. This ensures high light transparency and also has wear-resistant and impact-resistant functions, thus protecting the ring-shaped LED light strip 4.

[0030] refer to Figure 1 A silicone sealing ring is snapped into the joint between the decorative cover 2 and the lampshade 3. The decorative cover 2 and the lampshade 3 are installed together on the side away from the annular LED light strip 4 to form a sealed structure. This sealed structure prevents dust and liquid from entering, thus protecting the annular LED light strip.

[0031] refer to Figure 1 The decorative cover 2, lampshade 3, and ring-shaped LED light strip 4 are all threaded with screws 6 at their bottoms. These components are then bolted to the front end of the cordless drill body 5 using the screws 6.
